Section 2 - 2400-A16.
Intech Micro 2400-A16 Station.
The 2400-A16 is a high quality, high accuracy I/O station (input/output
expansion station), designed for a wide variety of applications.
Up to 16 Isolated Universal Analogue Inputs, with Plug In Terminals.
Each Input is fully Isolated and Individually Selected & Scaled.
RTD, T/C, mA, mV, V & Pulse/Digital as follows:
RTD: Pt100/Pt1000, -200~320°C to -200~800°C.
T/C: B, E, K, J, N, R, S, T, with CJC.
mA: 4~20mA, 0~2.5mA.
mV: -25~25mV to -200~200mV.
V: 0~1V to 0~15V.
Pulse/Digital: Meter pulses, Counting and Frequency.
Max speed 2500Hz.
Four Isolated Digital Inputs.
State or Count.
Max speed 8000Hz.
Two Analogue, Isolated, 4~20mA Outputs.
Two Isolated, Relay Outputs for alarm or control.
Comms Ports (connecting to eze):
Port 1: Isolated RS485.
Port 2: Isolated RS485.
USB programming port via XU-USB programming key.
2400-A16 Notes:
1. More than one 2400-A16 can be added to a ezeio controller.
2. The
ezeio Controller will accept up to 40 inputs total per ezeio controller (this also includes the 4 analogue inputs
on the ezeio controller if they are used).
3. The 2400-A16 is available with 2 options for the number of analogue inputs: 8 inputs or 16 inputs.
Adding a 2400-A16 station to an ezeio Controller.
Follow these steps to add one or more 2400-A16’s:
Disconnect both the ezeio Controller and 2400-A16 from the power supply.
First is to connect the 2400-A16 to the ezeio Controller’s ‘ModBus 485’ port.
The 2400-A16’s comms ports 1 & 2 are both Modbus RTU RS485 capable.
Connection to the ezeio Controller ‘ModBus 485’ port is by using a standard Ethernet cable plugged into the ezeio
Controller and broken out to twisted pairs.
Two of these pairs are used to connect to one of the 2400-A16 RS485 ports, to the ‘ModBus 485’ port of the ezeio
Controller as follows:
Blue pair: Blue = 70 on 2400-A16 comms.
Blue/White = 71 on 2400-A16 comms.
Brown pair: Brown = 74 on 2400-A16.
Brown/White = not connected.
