3.0 Installation
The Detcon Model 880 PLC is a wall-mount enclosure, and can be mounted anywhere that is rated safe for
NEMA 4X enclosures. The enclosure is equipped with four (4) wall-mounting brackets for easy wall mount
installations. Care should be given to prevent sharp objects from colliding with the touch screen display as
damage to the display may cause the unit to become inoperative. The screen can be cleaned with a mild
detergent and a lint free cloth. Never use an abrasive cleaner on the display.

2. For Serial Units (880S), connect the RS-485 Modbus™ network to the terminal blocks labeled
“Primary RS-485 , ” “A , ” “B , ” and “Shld” (Figure 8). Ensure that the network is properly laid out.
Proper layout of the RS-485 network is important for correct operation. Refer to Appendix A (RS-485
Integration and Wiring) for proper network layouts.
WARNING: The use of the 24VDC output to power external components should be restricted to no
more than 4Amps maximum (96 Watts). This equates to 32 sensors and/or field devices, maximum.
Care should be taken to insure that the total current of equipment utilizing this power does not exceed
the 4Amp rating, as this may cause detrimental damage to the unit and will void the warranty.
