EH0*A is the voltage-output isolator for a 1–5 V DC input and one 1–5 V DC output.
EH0*A is listed for MHC signal-conditioner nests; Yokogawa excludes EH0 output cards from MHM nests.
Check the receiving device and parallel connections for EH0*A against the documented minimum output load of 2 kohms.
EH0*A provides voltage output. Yokogawa lists EA0 for 4–20 mA output, so confirm the actual field signal before replacement.
For EH0*A, compare the nest terminals, polarity and receiving-device connections with the applicable drawing, then perform a documented loop check.
For EH0*A replacement, confirm style and assembly compatibility with the installed system before selecting another revision.
Include EH0*A, the complete tag, MHC nest model, receiving-device load and quantity so the supply can be matched to the existing loop.
Send the exact EH0*A nameplate, quantity, installed Yokogawa system, terminal hardware, destination and clear photos. Availability, condition and compatibility will be confirmed before quotation.
Verify the cited document revision and its applicability to the complete model, style and installed assembly. Family-level documentation does not establish interchangeability for an unlisted suffix.
