Product Description
The 812.66.04 is an I/O ANALOG OUTPUT MODULE 4CHANNEL 10V created by Reliance Electric. This card has a bare front panel with only one LED light that is marked ACTIVE. The 812.66.04’s circuit board has sixteen integrated circuits that go from the front of the card to the back. The 812.66.04 has eight orange PCB electrolytic capacitors and a yellow strip capacitor. There are two large black relay boxes. The first relay box is labeled Vi, NC, NC, SECON 12SCR2S05-M, GO, +VO, AND GI. The second relay box is labeled Vi, Gi, SECON 12SRR2D15-M, TP, +Vo, COM, TP, -Vo. The output module uses eight small black transistors and a small silver transistor. There is a blue tower in the front a white block near the back with 22R-J, 5W-KM-8 written on it and two smaller black boxes with 253.16.01 F 0613 written on one and 253.1601 F 0550 written on the other. The 812.66.04 card has eight variable resistors four are a pale blue while the other four are a dark blue. All of the variable resistors have a small gold screw at the top right corner of each box. This golden screw is used to adjust each variable resistor. At the very back of the circuit board is a large male terminal connection point. This male connection point takes up the entire back edge of the circuit board. Refer to the publication of Reliance Electric like manuals or data sheets to learn more.
