It features 18 terminals in total, supporting up to 16 DC I/O points, and is intended as a removable terminal strip for use with a range of DC I/O modules in the SLC 500 family, including 1746-IB16, 1746-IC16, 1746-IH16, 1746-ITB16, 1746-ITV16, 1746-IV16, 1746-OB16, 1746-OBP16, 1746-OV16, 1746-OVP16, 1746-IN16, 1746-IG16, and 1746-OG16. The blue housing identifies it as the DC I/O terminal strip used with these modules, and the 1746-RT25B designation is documented in SLC 500 hardware manuals as the Replacement Terminal Block for DC I/O configurations.
