Analog Outputs Applications using the 505E analog outputs must have the desired analog value assigned or configured to a specific output. There is a choice of six possible 4– 20 mA output drivers of which to use to display a parameter externally. The analog output connections for the 505E are shown in Figure 2-7. All 505E analog outputs can drive into a maximum of 600 Ω. Refer to Chapter 4 of this manual for a complete list of programmable analog output options. Actuator Outputs The two actuator output drive currents can be programmed to interface with Woodward Governor Company actuators (typically 20–160 mA drive currents) or non-Woodward actuators (4–20 mA drive currents). Each actuator output can be individually configured to interface with Woodward or non-Woodward type actuators. Actuator drive current is selected in the Program Mode. Maximum impedance for each 4 to 20 mA actuator output driver is 360 Ω (actuator impedance + wire resistance). Maximum impedance for each 20 to 160 mA actuator output is 45 Ω (actuator impedance + wire resistance). Dither is available for either output. Each actuator driver senses the drive current to allow over- and under-current shutdowns. Refer to Table 4-1 for driver details. In addition, an eleven (11) point actuator linearization adjustment curve is available through the Service Mode for each actuator output (see Service Mode adjustments in Volume 2). Relay Outputs There are eight relay outputs available from the 505E. All relay contacts are Form C type contacts. For relay load ratings, refer to Appendix A in Volume 2. NOTE Before installation verify that the 505E’s relay contacts meet the power requirements of the circuit with which it is being interfaced. Interposing relays are required, in cases where the interfaced circuit demands relay contacts with a higher power rating.
If interposing relays are required, it is recommended that interposing relays with surge (inductive kick-back) protection be used. Improper connection could cause serious equipment damage. Two of the eight relay outputs available are dedicated to a function and are as follows: • Shutdown relay—de-energizes for any shutdown condition • Alarm relay—energizes for any alarm condition The remaining six relays can be programmed to energize upon a function change of state or an analog value level. Applications requiring programmable relay outputs must have the desired switch condition or specific analog value assigned to them. Refer to Chapter 4 of this manual for a complete list of programmable relay output options.
