Feeds PWM output per IEC 61851 to each channel, with isolation tested at 707 V DC between the module and the control circuit. Rated for 24 V DC supply, includes diagnostic alarms, channel-status green LEDs, and a red ERROR LED. Firmware update is supported; I&M data is available from level 0 through 3 for asset tracking. Mounts horizontally on standard DIN rail. Width 20 mm, depth 58 mm; bus communication is supported. Accepts unshielded cable runs up to 30 m on the control pilot lines, using BU type B0 or B1 base units. Degree of protection IP20; pollution degree 2, typical for clean indoor environment. ## Comparison with similar MPNs The 6AG1242-6TM10-2BB1 is a dedicated EV charging controller. Other S7-1500 signal modules in the 6AG1* range — such as the 6AG1123-2DB03-2AX0 digital input or 6AG1231-5QD32-4XB0 analog input — serve different I/O roles and are not functional substitutes for this IEC 61851 PWM controller.
