Termination board

The termination board provides ports or terminals for power, internal or external communication, and
I/O connections (Figure
controller, positive temperature co-efficient fuses (PTC) and many other safeguards to protect the
remainder of the system from electrical damage. This board supports all outside communications and
I/Os. The termination board is low cost and field-replaceable. It operates on either 12 VDC or 24 VDC.
Figure 2-12 shows board components on the primary and secondary sides.
The primary component side (left on
removal of the rear cap. It provides interfaces for power, I/O, external communication connections,
and local communication options. This side features:
 Power connection and indicators:
 Power terminal connector (J1)
 1 Power monitor status indicator LED (D1)
 1 Voltage Regulator (5 VDC) status indicator LED (D2)
 I/O connections:
 2 DIs and 2 DOs (J2)
 Local communication interface (MMI) for operator access (depending on purchased option,
onboard interface connects internally to external explosion-proof port):
 USB host interface (J5) or
 Optional RS-232 (J7)
 Communications:
 Ethernet interface (J3) with 3 LED status indicators (D11, D12, D13)
 2 serial ports (RS-232/RS-422/RS-485 software selectable) (J8 and J10)
 Onboard security:
 1 Security Toggle Switch (S2)
 1 Security Switch Status indicator LED (D3), software programmable
 1 status indicator LED (software programmable, D4)
 Reset button (S1)
The secondary component side (right on
interfaces for internal connections.
 Transient protection
 EMI/RFI protection
 PTC fuses
 Voltage regulator for digital controller (VR1)
 Connector for the Analytical Processor Board (J12, internal connection)
 Connector for the Digital Controller Board (J4, internal connection)
