Relay Modules
Application
The INNOTECH range of Relay Modules are designed for applications
where up to eight individual 0-10VDC control signal inputs are
required to control up to eight individual stages of heating or cooling
in air conditioning and associated systems. The switching threshold
for the control signals are as in the table below.
