figure 2) to intrinsic safety barriers that satisfy the following parameters for each set of terminals.

Main 4-20 mA: Ui = 30 V, Ii = 130 mA, Pi = 1W, Li = 0.55 mH, Ci = 10.5 nF

XMTR circuit: Ui = 28 V, Ii = 100 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF

Limit Switch 1 (LS1): Ui = 16 V, Ii = 76 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF

Limit Switch 2 (LS2): Ui = 16 V, Ii = 76 mA, Pi = 1W, Li = 0 mH, Ci = 5 nF
