[. . . ] Via an external 500- resistor, an actuator with an input impedance of 500 can be used as 0 to 20 mA device. Specifications ·Twelve outputs (AO1 to AO12) 0 to 10 Vdc (+10%) output 0 to 20 mA output current (via external 500- resistor, see above) 0. 1 mA max. sink output current ·Protected inputs up to 24 Vac ·8-bit resolution ·±100 mV/±1 LSB accuracy (1 LSB = 43 mV) ·±100 mV/±1 LSB zero point (1 LSB = 43 mV) The relay modules are supplied via the special relay connection of the controller (terminals 65/66) IMPORTANT Important during connection: 1. Under no circumstances may a relay module be connected to the reference voltage. Several relay modules can be connected in series via the bridged terminal pair: Plus pole: Terminals 11/12 of the relay Minus pole: Terminals 13 to 16 of the relay MCD 3: L (Fig. left) Terminal 17 controls the changeover contact K3. Terminal 18 controls the ON contacts K1, K2. Ground can be looped through terminals 2/3. 19 EN1R-0144GE51 R1008 EXCEL 100C INSTALLATION INSTRUCTIONS MCE 3: M (Fig. left) Terminal 16 controls the ON contact K3. Terminal 17 controls the changeover contact K2. Terminal 18 controls the changeover contact K1. IMPORTANT It is not allowed to draw more than 300 mA out of terminal 65/66. The number of MCE and MCD modules that can be used depends only on the available AOs. watchdog alarm terminal 69 or 6 MCD 12 relays EN1R-0144GE51 R1008 20 EXCEL 100C INSTALLATION INSTRUCTIONS Terminal Assignment for Relays and Actuators N Connection of external relays. Each analog output can be connected to an external relay which has similar data to the relays described under the U. S. and European Specifications chapter. The impedance of the relay must be a min. of 500 for an output voltage of 11 V; an impedance of less than 500 can cause erroneous output voltage. The output current is limited up to max. 20 mA. O Type of connector for actuators with standard input signal 0 to 20 mA, but the sensor input impedance must be 500 . Each channel can be used as an analog output 0 to 10 V, or, respectively, as current output 0 to 20 mA with an external 500 impedance. The outputs are protected against overvoltage and overload 24 Vac. 21 EN1R-0144GE51 R1008 EXCEL 100C INSTALLATION INSTRUCTIONS Connection of Alarm Relays 55 56 57 58 59 60 61 62 63 64 65 - 66 + 67 68 69 not used 70 71 11 12 13 14 15 16 17 18 The selection of a signal transmitter for the watchdog alarm is optional. It is recommended that a switch for turning off the alarm be provided. NOTE: Terminal 69 is used to control the module MCE 3, only. [. . . ] In order to operate the SAF 25, the reference voltage from terminal 67 of the controller device must be connected to terminal 2 SAF 25. 41 EN1R-0144GE51 R1008 EXCEL 100C INSTALLATION INSTRUCTIONS Further Connection Examples F VMP (10 k total resistance) must be used for the feedback potentiometer. Connections as shown. G TF26 must be used for temperature sensing. Connections as shown.
