Yokogawa TA40-0N 40-Point Terminal Unit Style S1

The Yokogawa TA40-0N 40-Point Terminal Unit Style S1 is a 40-terminal block that directly interfaces with Yokogawa FA-M3 PLC I/O modules by converting the module’s connector interface to European-style screw terminals (M2 screws) for direct wiring of field signals, eliminating the need for separate cables or adapters. Its slim, space-saving design mounts directly to the I/O module with screws, providing 0.5 A per point across all 40 terminals, with a conductor size range of 0.08–0.26 mm² (AWG 23–28) and a rated voltage of 5–24 VDC (operating range 4.5–26.4 VDC). The unit weighs about 50 g and operates from 0 to 55°C, making it suitable for manufacturing lines, process control, and machine automation where reliable field signal termination is required and compact wiring layouts are a priority; it also supports temporary testing connections. Common replacements include Yokogawa TA50-0N (connector terminal block version) and TAS40 series terminal blocks (MIL connector type), but the TA40-0N Style S1 remains the dedicated 40-point option for direct FA-M3 I/O interface wiring.
