HMDW110 series transmitters are designed for a supply voltage range of 10 ... 28 V DC. The minimum required voltage depends on the loop resistance (0 ... 600 Ω) as shown below.

With HMDW110 series transmitters ordered with analog output, you must always connect the first current loop (terminals 5 and 6) to power the transmitter. With models HMD110/112, HMW110/112, and HMS110/112, connecting the second current loop (terminals 7 and 8) is optional.
