CN82 - Relay Drive Output (Transistor Output)
Pin 1 - Common
Pin 2 - Spare (not used)
Pin 3 - Transistor collector out
Pin 4 - +12 V
Note:
Depending upon the product/application specific micro-processor chip installed, this port, in
conjunction with one of Gullco’s optional auxiliary relay modules, may be used to activate
such things as pneumatic solenoid valves, safety circuits, etc. that may be part of the
automatic cycle routine.
Pin 3 and Pin 4 are typically used to energize the coil of an optional auxiliary relay module.
CN84 - Optically Coupled Output Signal
Pin 1 - Emitter
Pin 2 - Collector
Note:
This port is typically configured to activate at the same time as CN82, providing an optically
coupled output signal as an alternative to a transistorized output.
Caution:
Even though this control and its input and output ports have been designed to be as non
destructible and as isolated and durable as possible, extreme radiated high frequency
bombardment may cause a malfunction of the control. Gullco recommends that they be consulted
in such instances.
