Recommended Non-Isolated Active Transmitter with HCPL-4200 Isolated Receiver for Simplex Point-to-Point 20 mA Current Loop. receiver, can be used at the isolated end of current loops. Cross talk and common mode coupling are greatly reduced when optical isolation is imple- mented at the same end of both loops, as shown. The full duplex data rate is limited by the non- isolated active receiver current loop. Comments mentioned under simplex configuration apply to the full duplex case. Consult the HCPL-4100 transmitter opto- coupler data sheet for specified device performance. Half Duplex The half duplex configuration, whether point-to-point or multidrop, gives non- simultaneous bidirectional data flow from transmitters to receivers shown in Figures 22a and 22b. This configuration allows the use of two wires to carry data back and forth between local and remote units. However, protocol must be used to determine which specific transmitter can operate at any given time. Maximum data rate for a half duplex system is limited by the loop current charging time. These considerations were explained in the Simplex config- uration section. Figures 22a and 22b illustrate half duplex application for the combination of HCPL-4100/-4200 optocouplers. The unique and complementary designs of the HCPL-4100 transmitter and HCPL-4200 receiver optocouplers provide many designed-in benefits. For example, total optical isolation at one end of the current loop is easily accomplished, which results in substantial removal of common mode influences, elimination of ground potential Figure 19.
