3 Motherboard Interface PCB

(P/N 10-0215)

The HA20 Motherboard shown in Figure 3.2 is the interface between 
the Display / CPU assembly and all other system I/O devices. The 
Display / CPU assembly attaches to the motherboard with 4-standoffs 
and connects via ribbon cable to S1. Several input options, described 
in the following sections, are available that may be installed into the 
Sensor Input Option P1 connector located on the lower left side of 
the motherboard. The middle position P2 connector is for the 10-0223 
4-20mA Output option and the right position P3 connector is for the 
10-0222 Discrete Relay option. Other option devices such as Modbus 
RTU RS-485, Ethernet and a data logger may also be installed to 
connectors located on the Motherboard.

The  Motherboard  PCB  contains  a  24 VDC  universal  input  (100-
240 VAC)  switching  power  supply  with  up  to  350mA  available  at 
TB3  Auxiliary  Power  Output  terminals  (Figure  3.1).  If  AC  power  is 
unavailable, or if a DC battery back-up supply is needed, TB1 provides 
terminals  for  DC  power  input.  Blocking  diodes  isolate  internal  and 
external DC supplies as shown in Figure 3-1.

2 Amp, 250V, 5x20mm fuse located under

terminal cover.

WARNING

: For continued protection against

fire replace only with same type and rating of fuse.

TB2  offers  field  terminals  for  a  remote  alarm  reset  switch. The 
motherboard also includes alarm relays 1 & 2 (K1 & K2) and their 
indicating LED’s. TB4 provides field wiring terminals for these relays. 
TB5  is  for  connection  to  the  85-240 VAC  power  source.  J2  is  a 
2-pin connector for powering the optional part # 1000-1892 audible 
annunciator.
