Design Equations:
VOUT / ILOOP = K3 (R5 R3) / R1 + R3)
K3 = K2 / K1 = Constant = 1
Note:
The two OP-AMPS shown are two separate LM158, and not two channels in a single dual package,
otherwise the loop side and output side will not be properly isolated.
Figure 21. 4 to 20 mA HCNR200 receiver circuit.
Design Equations:
(ILOOP/Vin)=K3(R5+R3)/(R5R1)
K3 = K2/K1 = Constant ≈ 1
Note:
The two OP-AMPS shown are two separate LM158 IC’s, and NOT dual channels in a
single package, otherwise, the LOOP side and input side will not be properly isolated;
The 5V1 Zener should be properly selected to ensure that it conducts at 187μA;
