Module B875–200 Configurable A/D Input, Quick Start Test
(Original Document)
About us
General
Quick start tests for the following modules are described below:
NOTE: This module has had nyogel grease applied at the factory to the connector pins to ensure good terminal block connections. Do not remove this grease.
Isolated Voltage Input (-10 — +10 V)
Use the following procedure to configure the module as follows: eight channels (B875 in the I/O map), AS–5B31006A isolated voltage input pack, and four samples to be averaged.
Step
Action
1
Insert eight AS–5B31006A voltage input packs.
2
Set all eight-position DIP switches to left (viewed from rear of module when held vertically). This setting selects eight channels.
3
Set two-position jumper so that pins T1, T2, and T3 (located below access hole on left side of module) are not jumpered. This setting selects four average.
4
Wire + side of field device to input terminal 3 (VIN HIGH).
5
Wire -side of field device to terminal 4 (VIN LOW) on AS–8535-000 high-density connector.
Note: Remove keying tabs on AS–8535–000 high density connector prior to installing module.
6
Determine which channel and slot locations are to be used.
7
Stop controller, remove power, and insert module in housing.
8
Reapply power
9
I/O map module as a B875, registers 30001—30008 binary.
10
Start controller.
11
Confirm that module’s active light is flashing.
Note: Active ON steady = OK. The active light may also be blinking for one of two reasons: the input to the module is out of range; the selected channel (SW1—SW8) has no input pack installed.
12
Call up appropriate mapped registers of B875 using programming panel.
13
Using measurable voltage source of field device, vary input voltage to B875. Compare these values to those in table below.
The following table shows the signal to output value relationship

Isolated Current Input (-4 — +20 mA)
Use the following procedure to configure the module as follows: eight channels (B875 in the I/O map), AS–5B32001A isolated current input pack, and four samples to be averaged.
Step
Action
1
Insert eight fusible resistors shipped with AS–5B32001A input packs.
2
Insert eight current input packs (AS–5B32001A)
3
Set all eight-position DIP switches to left (viewed from rear of module when held vertically). This setting selects eight channels.
4
Set two-position jumper so that pins T1, T2, and T3 (located below access hole on left side of module) are not jumpered. This setting selects four average.
5
Wire input terminal 3 (VIN HIGH), 4 (VIN LOW) and 1 (CHASSIS GROUND) on AS–8535–000 high density connector as shown in typical field circuit connections for current inputs diagram, above.
Note: Remove keying tabs on AS–8535–000 high density connector prior to installing module.
