2.5.1 ISOLATED ANALOG INTERFACE CONNECTIONS
Table 2-1 and Table 2-2 describe the available input and output signals at
the DB25 connectors for standard ASD units and the SG compatible
interface. Table 2-3 describes the available input and output signals at the
DB9 connector for ASD units with the EtherCAT interface option. Section
2.9 provides a drawing of the rear panel input/output connector locations.
Table 2-1. Analog Interface Signals. Standard ASD Pin-out (DB25)
PIN # PIN NAME IN/OUT DESCRIPTION
1 I_MON A/OUT a 0-10 VDC monitor signal (or 4-20 mADC) that indicates zero to full scale
output current
2 V_MON A/OUT a 0-10 VDC monitor signal (or 4-20 mADC) that indicates zero to full scale
output voltage
3 P_MON A/OUT a 0-10 VDC monitor signal (or 4-20 mADC) that indicates zero to full scale
output power
4 V_MODE D/OUT (*) LO indicates the unit is not in voltage mode, HI indicates the unit is in
voltage mode if I_MODE is low. If both I_MODE and V_MODE are HI, it
means power mode.
5 I_MODE D/OUT (*) LO indicates the unit is not in current mode, HI indicates the unit is in
current mode if V_MODE is low. If both I_MODE and V_MODE are HI, it
means power mode.
6 STATUS D/OUT (*) LO indicates output disabled, HI indicates the output is enabled.
7 FAULT D/OUT (*) LO indicates normal operation, HI indicates a fault.
8 DOUT_REF IN Used to define the output high level of the digital outputs. If not
connected, the output high is 12V. If connected to 24Vdc, the output high
is 24V.
9 GND common Same as pin 16
10 +24Vdc OUT +24VDC, same as pin 17
11 I_PROG A/IN a 0-10 VDC analog input signal (or 4-20 mADC) that programs zero to full
scale output current
12 V_PROG A/IN a 0-10 VDC analog input signal (or 4-20 mADC) that programs zero to full
scale output voltage
13 P_PROG A/IN a 0-10 VDC analog input signal (or 4-20 mADC) that programs zero to full
scale output power
14 START/STOP D/IN (**) LO disables output, HI enables output.
15 RESET D/IN (**) LO to HI transition clears faults and warnings.
16 GND common Same as pin 9
17 +24Vdc OUT +24VDC, same as pin 10
18 GND common Same as pin 9
19 GND common Same as pin 9
20 Not used
21 Not used
22 RS-485 enable D/IN A high level will disable the Ethernet Interface to be able to use Modbus
over RS-485
23 RS-485 A D/IO Modbus interface over RS-485
24 RS-485 B D/IO Modbus interface over RS-485
25 RS-485 GND common Ground for serial interface (it is not isolated from the common ground)
Digital signal levels:
(*) Digital output low is 0V (<0.5V), output high is either 12V or 24V (+/-1V), depending
on pin 8.
(**) Digital input low is 0.5V or lower, input high is 8V or higher.
