Function

High-precision analog input

It provides 8 4-20 mA current input channels with 16-bit resolution (330 nA/ bit), suitable for high-precision signal acquisition.

Supports the power supply of the 2-wire transmitter circuit (20-30V DC), and no external power supply is required.

High isolation:

The isolation between channels and from channels to the backplane provides a 150 dB common-mode rejection ratio to reduce noise interference.

24V DC overvoltage protection to enhance the durability of the module.

Open-circuit detection

Detect open-circuit input for up to 5 seconds to ensure system reliability.

Supports under-range (3.2mA) and over-range (21mA) detection.

Easy to install

Use the 1771-WH wiring arm. It is recommended to be used in conjunction with the RTP-4 terminal to simplify the wiring.

It is installed on the 1771 I/O rack and requires power-off operation to avoid damage.

Compatibility

Seamlessly integrated with PLC-5 controllers (such as 1785-L40L), and supports RSLogix 5 programming.

Data can be transmitted to HMI or DeviceNet devices via 1785-ENET or 1788-CN2DN.

Diagnostic function:

Support RSLogix 5 diagnosis to monitor input status and module health conditions.

Application scenarios

Process control: Collect 4-20 mA signals such as pressure, temperature and flow rate, which are used in the chemical and food and beverage industries.

Manufacturing industry: Monitor sensor data on the production line, such as liquid level or weight.

Data recording: Collect process data and transmit it to SCADA or HMI (such as 2711-M3A18L1).

Traditional system maintenance: Expansion or replacement of analog input for old PLC-5 systems.

Distributed control: When used in conjunction with the 1771 I/O rack and Remote I/O, it is suitable for distributed systems.
