The BSPI232 signal isolator provides galvanic isolation where common mode voltages or earth loop problems occur. The BSPI232 is powered by the input signal, therefore it can only be offered in current input versions with a zero offset (4 – 20mA, 10 – 50mA). Typical output is 4-20mA but can be 1-5V by using different output terminals. A green L.E.D. on the module front gives a clear indication of input signal and will change its intensity in relation to input signal level. Load trim adjustment (full scale) is placed on the module front. Zero tracking is automatic and requires no adjustment. Facility for in-process monitoring is provided for input and output.
INPUT: Terminal 1(+) to Test Socket (-) 20mA = 200mV.
OUTPUT: Terminal 8(+) to Terminal 6 (-) 20mA = 200mV.
