When ordering, add the rated voltage to the model number. Rated voltages are given in the coil ratings table in the specifications. Example: MKS2XTIN-11 AC240 Rated voltage 2. Refer to Terminal Arrangement and Internal Connections for all wiring diagrams. Accessory (Order Separately) Connecting Socket and Hold-down Clips Classifications Built-in diode Socket Hold-down Clip Back-connecting Socket PCB Mount No P7M-06P No P7MF-06 PYC-A2 Front-connecting Socket DIN Track or Panel Mount Yes P7MF-06-D Note: 1. The P7M-06P, P7MF-06, and P7MF-06-D can be used with models for DC loads with an SPST-NO or SPST-NO/SPST-NC contact form or with models for AC loads with an SPST-NO or SPST-NO/SPST-NC contact form. 2. The P7MF-06-D has a built-in diode and can thus be used only with Relays with DC operating coils. Do not use it with a Relay with an AC operating coil. 3. Refer to Gang Mounting in the Safety Precautions section for the conditions required to gang mounti multiple relays side-by-side. 4. Use the Clips to securely mount the Relay and prevent it from falling due to vibration or shock.

If the L/R of an inductive load exceeds 7 ms with a Model for a DC Load, the arc interruption time must be less than approximately 50 ms to use the Relay. Design the circuit so that the arc interruption time is 50 ms or less. 2. These values apply to a switching frequency of 30 times per minute.
