Analogue Input Expansion - Using 2100-M Analogue Input Multiplexer.
Analogue input expansion can be achieved using up to four 2100-M, 16 Channel, Analogue Input Multiplexers. This
gives a total of 76 analogue inputs. Control for the 2100-M is through the AO1 and AO2 on the 2100-A
16
. (Refer Note
4 below.) One analogue input is required per 2100-M, and each 2100-M input must be of the same type and range. The
remaining 2100-A
16
analogue inputs can be used for any other type of input.
Option 1. 5 Wire Connection Diagram.
This uses 5 wires for the first 2100-M, with 2 additional wires for each additional 2100-M. In this configuration the
analogue inputs are differential. The maximum peak input voltage is 18V.

2100-M
Note 1.
The 2100-A16 resolution on 2100-M
multiplexer inputs is 12 bits (4096 steps)
Note 2.
All cables must be screened, and the screens
earthed at one end only.
Note 3.
Analogue Input expansion is also possible
using the EXPO-3. Refer to the connection
diagram below.
Note 4.
When 2100-M multiplexers are used:
AO COM connects to CS COM;
AO 1 is used for the RESET pulse;
AO 2 is used for the CLOCK pulse.
AO 1 & AO 2 are not available for any other use.

Option 2. 4 Wire Connection Diagram.
This uses 4 wires (2 pair) for the first 2100-M, with 1 additional wire for each additional 2100-M. In this configuration the
analogue inputs single ended. i.e. All the -ve inputs are all commoned.
