HIMA F 3237 Safety Related 8 Fold Input Module

Q: What parameters are automatically checked during operation for this module?

The module automatically tests its entire operation including switch-on and switch-off capability, crosstalk of input circuits via a walking 0 test, input filter functionality, correct general module operation, and sensor line short-circuits or wire breaks.

Q: How are non-standard proximity switches integrated into the line break supervision system?

For proximity switches outside the DIN 19234 standard that deliver low current in a non-damped state, a 47 kOhm parallel resistor can be switched into the circuit to raise the output current to 170 microamps, ensuring correct line break detection.

Q: What are the line length and impedance constraints for sensor connections?

The maximum permissible line length is 1000 meters for a cable cross-section of 0.5 square millimeters, and the maximum line impedance must be less than or equal to 50 Ohm in compliance with DIN 19234.

Description

The HIMA F 3237 is a safety-related 8-fold input module designed for the connection of safety-related proximity switches, proximity switches complying with DIN 19234 (NAMUR), and resistor-wired sensors. This module provides line monitoring capabilities to detect short-circuits and line breaks in the sensor lines, ensuring safe operation within requirement classes AK 1 to 6. The HIMA F 3237 executes completely automatic test routines during operation, checking parameters such as switch-on and switch-off capability, crosstalk via a walking 0 test, input filter functionality, and overall module operation.

Features

Supports 8 input channels for safety-related sensor applications.
Monitors connecting lines for short-circuit and line break conditions.
Fully automated self-test routines run continuously during operation.
Compatible with standard NAMUR proximity switches and non-standard switches, such as the P&F NJ 5-30GK-S1N, with a parallel resistor modification.
Enables redundant connections for proximity switch circuits.

Applications

Safety-instrumented systems (SIS) in industrial automation.
Proximity sensing and position monitoring in hazardous or critical environments.
Line-monitored sensor interfaces requiring requirement class AK 1 to 6 compliance.

Installation Guidelines

Ensure the front cable plug Z 7108 is correctly connected to the module faceplate.
Follow the specified lead mappings and core color coding for the LiYY 16 x 0.25 mm2 cable.
When using proximity switches outside DIN 19234, such as the P&F NJ 5-30GK-S1N, connect a parallel resistor rated at 47 kOhm, 0.25 W, and 5%.
For redundant configurations, follow the specified dual-module channel wiring arrangement.
