Description

The IC693ALG391 is a high-performance 2-channel analog current output module developed for the GE Fanuc Series 90-30 Programmable Logic Controller platform. This space-saving single-slot interface board converts 12-bit digital binary values received from the central processing host into stable, isolated industrial-grade analog output currents for precision control applications. Operating over standard output ranges of 4 to 20 mA or 0 to 20 mA, the module ensures synchronized loop updates by executing full internal digital-to-analog conversions on both channels simultaneously during every programmable controller CPU I/O scan loop. High-speed internal galvanic optical isolation buffers block high-voltage spikes and eliminate industrial electromagnetic noise interference between active field loop cabling and the low-voltage logic side backplane.

Features

Dual high-speed, individually isolated analog output channels driven by a dedicated internal 12-bit digital-to-analog converter framework.
Dual software-independent configuration profiles accommodating standard industrial 4 to 20 mA or extended 0 to 20 mA operational loops.
Integrated high-speed updating logic driving simultaneous data transformations across both channels within an approximate 5-millisecond execution interval.
Advanced active safety response mechanism allowing individual channels to instantly hold their last active output state or default directly to 0/4 mA during system stop or reset conditions.
Multifunctional circuit path routing allowing standard low-impedance current sourcing or configuration as a voltage source via simple external jumper links.
Heavy-duty optical isolation barriers engineered to continuously block electrical noise and common-mode transients up to 1500 volts between the field wiring terminal and controller logic.
Dual-input power architecture utilizing either standard isolated PLC backplane 24 VDC power lines or external auxiliary 24 VDC loop standby power supplies.

Applications

Variable speed drive frequency reference control and modulated speed sequencing loops.
Proportional flow-control valve positioners and pneumatic actuator balancing instrumentation.
Remote analog instrumentation recorders, loop controllers, and distributed processing interface units.
Paper mill, water treatment, and petrochemical processing cell parameter profiling.

Installation Guidelines

To ensure maximum equipment reliability, safety, and compliance with industrial standards, follow these structured engineering protocols during deployment.

1. System Power Safety & Slot Restrictions

CRITICAL NOTICE: MANDATORY DE-ENERGIZATION

Always confirm that the main controller baseplate power source is completely disconnected before inserting, adjusting, or extracting the module. Do not hot-swap under any circumstances.

The module can be placed into any standard I/O slot across any expansion or CPU baseplate.
To prevent power supply degradation and overheating, restrict population to a maximum of 6 master modules per CPU baseplate simultaneously.
Ensure that each installed module is routed to a physically isolated, independent network loop to avoid signal contention.

+-------------------------------------------------------------+
| [CPU] | [Slot 2] | [Slot 3] | [Slot 4] | [Slot 5] | [Slot 6] |
| Slot1 |  I/O LINK|  I/O LINK|  I/O LINK|  I/O LINK|  I/O LINK|
|       |  Master  |  Master  |  Master  |  Master  |  Master  |
+-------------------------------------------------------------+
        |__________ Max 6 Modules per CPU Baseplate __________|

2. Communication Cabling & Shielding Techniques

Signal Interference Mitigation: All field connections terminating at the 20-pin Honda-type front port must be routed through industrial-grade shielded twisted-pair (STP) cabling. This is critical to maintain RS-422/RS-485 balanced line signal integrity.
Drain Wire Grounding: Terminate the cable outer shield directly to the system frame ground or dedicated chassis ground bus bar to eliminate high-frequency electromagnetic noise.

3. Execution Sequence & Initial Power-Up

Verify Hardware Mounting

Confirm the module is firmly seated into the backplane slots and the top/bottom plastic clips are locked in place.

Connect Field Wiring

Secure the 20-pin Honda-type connector to the serial line leading to the first distributed slave device.

Apply Primary Power

Turn on the main chassis power supply and closely monitor the startup sequence diagnostics via the LED indicators.

4. Post-Installation Fault Recovery Operations

Link Instability Resolution: If a transient communication error, timeout, or packet loss occurs on the serial bus, utilize the integrated front-panel interface to restore normal system operations.
Manual Reset Execution: Firmly press the dedicated LINK RESTART manual pushbutton on the front faceplate. This overrides frozen error registers, clears network faults, and forces an immediate cold initialization of the serial communication link without rebooting the main PLC CPU.

O que acontece com as saídas do loop de corrente analógica se a CPU host entrar no modo STOP?

A resposta é determinada pelo jumper DEF 0 no pino 12 do terminal. Se não estiver jumpeado, os canais mantêm seu último valor ativo, desde que a alimentação de backup esteja conectada. Se estiver jumpeado, eles retornam imediatamente para 0 mA ou 4 mA, dependendo da faixa selecionada.

Como o módulo pode ser modificado para emitir um sinal de 0 a 10 V em vez de um loop de corrente?

Para configurar uma faixa de 0 a 10 V, o canal deve ser ajustado para a faixa de 0 a 20 mA com um jumper, e um resistor de alta precisão de 250 ohms deve ser instalado entre os terminais JMPVx e IOUTx em vez de um link de fio padrão.

Qual é o número máximo desses módulos que podem ser instalados em uma única placa base?

No máximo três módulos podem ser instalados por placa base se estiverem consumindo energia exclusivamente do backplane do PLC. Para superar esse limite e evitar sobrecarga na alimentação do backplane, uma fonte de alimentação externa de 24 VDC deve ser conectada ao bloco de terminais.

Como o módulo processa valores de registrador fora da faixa escritos pelo código do usuário?

O módulo usa um formato de complemento de 2 de 16 bits escalonado até uma contagem decimal de 32000 para saídas de corrente em escala total. Se um valor de dado inválido maior que 32767 for inserido, o software de programação rejeita a entrada e não aceita o valor.
