Configurable Limit Switch

General Description

This module contains two comparators and one or two relays for the monitoring of analog signals from 0-400 mV, 0-10 V or 0-20 mA. The input range, the operating mode, and the setting of the contacts can be programmed via DIL-switches on the rear of the unit.

• Two switching thresholds with status LEDs, adjustment via a 12-turn potentiometer
• Choice of one or two relays with double-throw contacts
• Selectable operating modes: limit switch, window comparator, two-position controller
• Programmable hysteresis (standard) and time delay (optional)
