ORC-HAGW-EXT-B


ORC-HAGW-EXT-C


Input Power 11V - 13V DC  (250mA)11V - 13V DC (200mA)
Analogue inputs 
8 in total on the top level connectors
Labelled (A1 - A8)
NTC 10K input

Example 10K NTC thermostat sensor at 12K resistance (approx 21 degrees) will pull down the 3V DC to 1.85V DC

If terminal shows 0V then there is a short
If 3.3V DC then the connection is open circuit or disconnected.

ORC-HAGW-EXT-C

ORC-WC-8 compatible

Solid state relay boards allowing PWM outputs for other use, example 240V actuators UFH, or Blinds etc.
YES, 
no resistors required
YES 
requires 500 ohm - 1K ohm resistor across PWM output and GND.
This will drop the 4V minimum output to 1 - 1.8V DC
Now the ORC-WC-8 can be used.
