IO-RM-4 - Sontay 4-Stage Relay Module

Relay module with 4 switching outputs from 1 analog input. 

Description

This range of relay modules is intended for use with BMS controllers to convert an analogue control output to various switching relay modes. Example applications include the control of raise/lower valves, damper actuators, pump changeover and boiler control. LEDs indicate correct operation and Hand/Off/Auto jumpers ease commissioning. Low current draw from 0-10Vdc controller output means that the IO-RM range works successfully with most BEMS controllers.

Features

• Fault finding LED indication
• Relay status LED indication
• Link selectable switching modes
• On/Off/Auto links for ease of commissioning
