KJ4001X1-CK1
The product is named Emerson KJ4001X1 – CK1 I/O Module. It is a key component within Emerson’s industrial automation product portfolio, designed to facilitate seamless input and output operations in industrial control systems.
2. Product Description

2.1 General Function
The KJ4001X1 – CK1 I/O module is an integral part of industrial control setups, especially those related to Emerson’s DeltaV systems. Its primary function is to serve as an interface between field devices and the control system. It can receive various types of input signals from sensors, such as analog and digital signals, and then process and transmit these signals to the central control unit. Conversely, it can also send out output signals to actuators based on the control commands received from the controller, enabling the control of industrial processes like the operation of motors, valves, and other equipment.
2.2 Key Features
- Versatile I/O Capabilities: This module likely supports a wide range of input and output signal types. It can handle analog inputs with different voltage and current ranges, such as ±1V, ±5V, ±10V, 0 – 20mA, and 4 – 20mA (both local and remote – powered versions). For analog outputs, it may provide signals like 0 to +10V, 0 to +5V, 0 to 20mA
