It is said 70EB01B-E has been obsoleted for long time, but we have 3pcs in stock and one year warranty

This item primary application areas include main and auxiliary control systems for thermal power plants, gas-fired combined-cycle units, steam turbines, and generators;

Integrated protection systems for hydroelectric, nuclear, and waste-to-energy power plants and substations, as well as interlocking control for large-scale chemical processing.

The 70EB01b-E must be used in conjunction with other modules from the same series—such as the 70EB (digital input), 70AB (digital output), and AI/AO (analog input/output) modules—to form a comprehensive signal acquisition and output system for the entire plant.

Key advantages include: long service life and high stability; circuit isolation capabilities that prevent field short circuits from damaging the controller; and a fault alarm indicator that enables rapid identification of board malfunctions, thereby significantly reducing downtime for maintenance.

Key electrical specifications are as follows:

Logic 0 (no signal): -30V to +3V DC

Logic 1 (contact closed): +11.2V to +30V DC

Single-channel input impedance: 15kΩ

Signal sampling/refresh rate: 50μs (supports high-speed pulse acquisition and rapid switching signal detection);

Channel capacity: Standard multi-channel isolated digital inputs; a single card integrates multiple independent acquisition circuits;
