Figure 18-13. Multi I/O Analog PCB Option
Multi I/O Analog PCB Option (686B612U02)
1. This option card occupies Expansion Board slot 5 (J connectors 1 and 2).
2. This option supports the capabilities of the Single Channel Analog Input (AI8) plus it adds 4
AIs (AI4-7) and 2 AOs (AO2 and 3). If used, AI8 of this option card requires one Group
5 Analog Device Module or equivalent that is listed in the Specifications table of Section 1.
3. This option card corresponds to database locatins for AI4-8 (see Configuration Table 5-4) and
AO2 and 3 (see Configuration Table 5-5).
4. It requires a Multichannel Analog ITB (686B617U01) and an ITB cable that connects to
controller J4.
5. The controller must be expansion ready.
6. This option is mutually exclusive with the Single Channel Analog Input PCB option. It is also
mutually exclusive with any option requiring the HART Modem PCB in slot 5.
7. In upper right corner of bottom side illustration: Jumper W1 is factory set for B to C, which gives
upscale reading (very hot) for an open thermocouple. If jumper W1 is connected A to B, it gives
a downscale reading (very cold) for an open thermocouple.
