Mechanical Relay Board

The hard wired relay board, MTI part #81097, provides
for a hard wired control system with interlock
capabilities utilizing mechanical relays. The relay
board is equipped with 8 mechanical relays with form
C contacts provided on the output. The board provides
for 3 LED indicators per relay. The LED indicators
are provided with diode protection and lamp
test diodes. In addition, the indicator circuits are
equipped with a dropping resistor in order to eliminate
the necessity for dropping resistors on the faceplate.
The switch inputs to the circuit board provide
for an unlock and lock position for each circuit.
The hard wired relay board, part #81097, also provides
for a jumper assignment of two emergency release
groups. The emergency release input points
are located at one end of the board, and the jumpers
are selectable for each relay circuit.
