The Allen-Bradley 1734-CTM POINT I/O Common Terminal Module provides expansion to a POINT I/O’s termination capability. It is part of the Bulletin 1734 series of POINT I/O modules. Install it on a 1734-TOP, 1734-TOPS, 1734-TB, or 1734-TBS terminal base assembly. Make sure that the mounting base is correctly keyed before installing the module. The 1734-CTM supports 8-channel higher-density modules and the management of field devices wiring to the POINT I/O solution. It can also be used as an external connection in common connections for three-wire devices.

The 1734-CTM Common Terminal Module features a keyswitch position of 5 and it has been tested at 1600 Vrms for 60 seconds of Isolation Voltage (Continuous Voltage Withstand Rating). It has a 10 to 28.8 Volts DC or 120 to 240 Volts AC supply voltage.  It has no enclosure. The 1734-CTM has a C-UL-US certification and it is UL Listed for Class I, Division 2, Groups A, B, C, and D hazardous locations. The operational temperature should be within a range of -20 to 55 degrees Celsius (-4 to 131 degrees Fahrenheit) range with a relative humidity between 5 and 95%, noncondensing for optimal performance.
