Description
The Honeywell 621-2200RC is an 8-point 230 VAC digital output module engineered for the Honeywell IPC 620 programmable logic controller and Universal I/O system. Installed within an IPC 620 full or half I/O rack, the module receives discrete control instructions from the central processor across the rack backplane and switches external AC field circuits. It operates as the physical actuator interface for machinery, switching loads such as motor starter coils, hydraulic and pneumatic solenoids, valves, alarms, and industrial pilot indicators.
Designed with individual channel isolation and optical coupling, the 621-2200RC prevents electrical noise, voltage spikes, and common-mode line transients generated by inductive field loads from reaching internal controller logic circuitry. The RC-suffixed designation provides factory-applied conformal coating over the circuit board assembly, ensuring long-term operational integrity in industrial locations exposed to moisture, chemical vapors, and particulate matter.
Features
- 8 discrete 230 VAC solid-state output circuits.
- Direct backplane compatibility with Honeywell IPC 620 full-size and half-size Universal I/O racks.
- Conformal coating (RC designation) protecting electronic components against harsh atmospheric contamination.
- Optical isolation between logic-level backplane circuitry and 230 VAC field wiring.
- Compatible with IPC 620-10, 620-15, 620-20, 620-25, and 620-35 programmable controller systems.
- Front-panel status indicators providing real-time channel state diagnostics for maintenance and loop checkout.

Connections / Interfaces
Field connections for the 621-2200RC are terminated via an 8-point top and bottom screw-terminal block assembly (catalog number 621-9949). The terminal block accepts up to two #14 MTW copper wires per terminal point. Internal jumpers at the terminal housing configure points per common power supply line, allowing flexible distribution of single-phase 230 VAC external source lines across the 8 switched channels.
