Please Note: Modbus Protocols are NOT available with the 2100-M
If you require a multiplexer with Modbus Protocols please view the 2400-A16
The 2100-M is used extensively in industrial plants, with proven reliability and accuracy. It comes complete and ready to operate in a compact DIN rail mount enclosure.
The 2100-M (previously the EXPO-3) can multiplex up to 16 analogue inputs, into one input of a PLC or a Data Logging System. It uses solid state switches, making it extremely reliable and durable.
The PLC only requires two digital outputs and one analogue input to select and receive data from the 2100-M. For each additional 2100-M added to the system, only one more analogue input is required. (The typical fan-out for most PLC's is up to eight 2100-M's)
The 2100-M-I and the 2100-M-R are on board input span programmable. The output can be configured to a selection of industry standard output signals.
Note 1) Minimum Range = Signal High - Signal Low.
Note 2) Maximum Range = Signal High - Signal Low.
Note 3) Sensor Break only applies to the RTD (-R) input model.
Note 4) Power supply 'H' is field selectable for 'M'; and 'M' for 'H'. Power supply 'L' must be ordered separately.
Notes on 2100-M-R (Input Range IR):
From the table above, you can chose a span (or Input Range IR) between -200 and +600°C. These are the limits - a span can not be chosen outside these limits.
However, to chose an actual span of -200 to 600°C is too wide to achieve good definition. I.e. If you want to see steps of 1°C or better, you will not achieve this with an actual span of -200 to 600°C. The minimum possible span is 20°C. The maximum possible span is 600°C. You need to chose a span that covers your working temperature range.
Examples of commonly used ranges include: 0~100°C, -50~50°C and 0~200°C.
Ordering code example for 2100-M with RTD Pt100 input (Input Model M = R), Input Range IR (or span) of 0~200°C, Output AO = 4~20mA, Channel Selection CS = Clock/Reset, Sensor Break SB = Upscale, Power Supply PS = 85~264Vac/dc:
2100-M-R- 0~200C - 4~20mA - CR - US - H
|Analogue Input Multiplexer:||16 Single ended inputs|
|Each Multiplexer is span programmable within the specified input type as per below:
2100-M-R = RTD Pt100 (-200~600°C) (-330~1100°F)
2100-M-I = 4~20 / 0~20mA
2100-M-V = mV & V (-25~500mV and 0~10V DC) - No longer available, use the 2400-A16.
2100-M-T = Thermocouple (-100~1700°C) (-150~3000°F) - No longer available, use the 2400-A16.
Note 1:Minimum Thermocouple span = 200°C (400°F)
Note 2:2100-M-T requires a PI-T transmitter
