Function

TTL signal transmission: The module supports TTL level signal output (high level 2.0- 5.25VDC, low level -0.2- 0.8VDC), which can be connected to any device that complies with the TTL logic level specification and is suitable for low-voltage signal control.

Sinking/Sourcing output: It provides 8 configurable sinking or sourcing output channels. Users can choose high-level or low-level logic to flexibly adapt to the requirements of different devices.

Fast response: The maximum signal delay time is 1 millisecond, making it suitable for control applications that require a fast response.

Low-power design: The backplane current is only 168 mA, the power consumption is as low as 2.2 W, and the heat dissipation is only 7.5 BTU/ hour, making it suitable for integration into high-density I/O systems.

Modular installation: The module is designed for single-slot installation and is compatible with 1771 series I/O racks. Wiring is simplified through the 1771-WC wiring arm, reducing installation and maintenance costs.

ESD protection: When installing, a grounding wristband must be worn to prevent electrostatic discharge (ESD) from damaging the module and ensure long-term reliability.

Application scenarios

Electronic device control: It is used to drive TTL compatible electronic devices, such as digital displays, counters, logic circuits or other low-voltage control modules, and is commonly found in electronic manufacturing and testing equipment.

Data acquisition and interface: In the data acquisition system, it serves as a bridge between the PLC and TTL logic devices (such as sensors, microcontrollers or interface circuits), transmitting control signals.

Laboratory automation: In laboratory or research and development environments, it is used to control precision instruments or experimental equipment to meet the requirements of low-voltage and high-speed signal transmission.

Communication system: In industrial communication equipment, it drives the TTL signal interface module, which is suitable for the control of telecommunication or network equipment.

Small-scale automation systems: In space-constrained or power-sensitive automation systems, it provides low-power TTL output control, suitable for small-scale production lines or packaging equipment.
