HIMA F3237 984323702 Input Module

Description

HIMA F3237 984323702 is an 8-channel safety related input module that serves as a critical link between field sensors and control systems in industrial automation architecture.

F3237 984323702

It adopts a redundant, security related processor system that allows for comprehensive self checking directly on the module. This means that during operation, it will continuously verify its integrity, thereby reducing the risk of undetected failures. The main self-test program includes checking for crosstalk between eight input channels and the functionality of input filters. In terms of signal detection, it follows strict standards: the 0 signal is recognized within the range of 0.35 ≤ ie ≤ 1.2 mA, while the 1 signal is recognized within the range of 2.1 ≤ ie ≤ 6.0 mA. This module also requires a line impedance of ≤ 50 ohms (in accordance with DIN 19234 standard). In terms of wiring, it is recommended to use shielded cables for on-site input circuits, while twisted pair cables can further improve performance. However, in interference free and short distance scenarios, such as inside well shielded cabinets, unshielded and non twisted pair cables can be used. However, it is worth noting that shielded cables are the best choice for achieving optimal anti-interference performance of analog inputs.
