The new DRTB Series thermocouple terminal
blocks are manufactured with thermocouplegrade alloys to guarantee accurate readings.
A built-in SMP-compatible female receptacle
accepts a miniature thermocouple connector.
The female connector allows the user to
connect to a handheld meter for applications
such as data collection, quality assurance
compliance, capability studies and trouble
shooting installation or repairs.
The plastic housing is made from gray
polyamide 6.6 thermoplastic resin with a
UL 94 V0 rating for 85°C. These
Shown with RECK1-10 cable, and the HH506RA datalogger/thermometer,
with RS232C interface.
thermocouple terminal blocks are fully
enclosed and require no end plates. The
screws and clamps are zinc plated, and
together they provide an excellent vibration,
maintenance free and corrosion resistant
connection.
DRTB terminal blocks mount on standard
35 mm DIN rails or 32 mm G-type rails,
and are identified with calibration type and
positive (+) and negative (-) connections.
Wire entry is funneled to allow quick wire
insertion even with stranded wire.
