What is the external scanner box? External scanner box for 720221 module; The use of a 720221 module always requires the External Scanner Box 701953
Voltage or temperature measurement (scanner method) Thermocouple (K, E, J, T, L, U, N, R, S, B, W, Au-Fe-chromel)
701953-L1: 16-CH Scanner Box (provided with 1 m cable)
701953-L3: 16-CH Scanner Box (provided with 3 m cable)
This is a multichannel input module capable of measuring up to 16 channels (subchannel’s DC voltage or temperature measured by TC) on a single unit. It consists of the module body (model: 720221) and external scanner box (model: 701953) and both units are always required to make measurements. Wires for voltage measurement or a thermocouple for temperature measurement are connected to terminal blocks (screwed type) of the external scanner box.
The input section is isolated between ground and terminal blocks and between subchannels. For the voltage measurement range and temperature measurement range (available thermocouple types and accuracy), see the module specifications described on page 5 of the ScopeCorder series DL850E/DL850EV/DL350/SL1000 manual. Both the maximum input voltage and maximum rated voltage to earth are 42 V (AC + DCpeak, 1 kHz or less).
