The Digital Input Expander allows 4 volt free inputs to be monitored by a single analogue input channel. The resultant analogue value can be decoded by the A to D function module in a BMS controller to produce internal digital status bits for alarm monitoring or other status input applications.
The IOR4 is intended for use with BMS controllers to convert an analogue control output to a binary, staged, or sequenced relay modes. LEDs indicate correct operation and Hand/Off/Auto jumpers ease commissioning.
The IOPC1-120 is designed to convert a single 0-10Vdc Input Signal to drive a 0-20V 50Hz phase-cut output, at 120VA, to drive larger valve and damper actuators.
The AUD converts a floating-point signal into a linear analogue output. There are Two inputs on the AUD, one to increase the analogue output and one to decrease the analogue output.
The IOMR1 is designed to provide a manual override of the output from a BMS Controller (or similar) and is particularly useful for commissioning or temporary control applications.
This IO module is used with DDCs to convert an analogue control output to a staged, reverse staged or sequenced relay output.
LEDs indicate correct operation and low current draw from 0-10Vdc controller means that the IOR6 can work successfully with most BEMs controllers.
