Product Introduction
The VE4002S1T1B2 is an 8‑channel isolated discrete output card in the Emerson DeltaV family, offering 24 V DC high‑side switching with optical isolation per channel. It is designed for modular I/O architectures, connecting control logic to field devices reliably and safely.
This module supports a variety of output modes, including continuous output, momentary pulses, and configurable timing, giving flexibility in controlling actuators, solenoids, relays, or other 24 V field loads. The isolation ensures field faults or noise do not propagate back into the control electronics.
The device is designed to mount in a standard I/O carrier or backplane and uses keyed terminal blocks to avoid wiring mis-match. Because of its compact size and robust construction, it fits well into control cabinets or distributed I/O racks.
Its operating temperature, shock, and vibration specs make it suitable for industrial environments.
