^1 The ES-M1(P)/M2(P) cannot be connected to the EH-422, 430, 440 or 290. ^2 During N.O. operating configuration, the off delay timer is 10 ms. During N.C., the on delay timer is 10 ms. ^3 Broken connection warning output is not available on the ES-M2 (P). ^4 The ambient temperature changes according to the following conditions when expansion units are added. When adding units, always attach them to a DIN rail (metal plate) and set the output current to 20 mA or less. 1 to 10 expansion units: 0 to 50˚C 32 to 122˚F 11 to 16 expansion units: 0 to 45˚C 32 to 113˚F
