• six (6) relays, four (4) Binary Inputs, and four (4) Analog Inputs
• relays can be configured to indicate status of six (6) different alarms
or status points
• independently-isolated Binary Inputs can be configured to report ON/
OFF status of four (4) controls
• Analog Inputs include input scaling and can report the status of four
(4) analog controls referenced to the dc bus

2.1.4 Filter Capacitor Board (A7)

Shown near top-left of silkscreen. Bolted to top of the Power Board
(A2). The capacitors (C1x) filter 'ripple' from the dc output.

2.1.5 AC Surge Suppressor MOV Board (A9)

Shown to left of AC Circuit Breaker (CB1) on silkscreen. Mounted to
top-left side of breaker bracket. Contains ac input surge suppression
and filtering. It is located for easy access, examination, and
replacement in case an input transient event should occur.

2.1.6 Serial Communications Adapter (A12) - optional

Shown above Ethernet Comm. Adapter (A22) on silkscreen. Up
to three (3) Serial Communications Adapter boards (A12) can be
plugged into the Main Control Board (A1) at locations P10, P11, and
P12. This option supports DNP3 and Modbus protocols, and can be
configured to support 2-wire or 4-wire RS-232 connections, or 2-wire
or 4-wire RS-485 connections.
