The relay options can be ordered for a new actuator or added to an existing MX and are listed as
follows:
OS = Standard S relays (4 total, 2 configurable, 2 complementary) and (1) Monitor, rated for 2 •
A/30VDC, 0.5 A/125 VAC
OA = Digital output R option (4), including Monitor, rated for 5 A/30 VDC, 250 VAC•
OB = Standard S relays (2), including Monitor, rated for 2 A/30 VDC, 0.5 A/125 VAC and Digital •
output R option (4), rated for 5 A/30 VDC, 250 VAC
OC = Digital output R2 option (8), including Monitor, rated for 5 A/30 VDC, 250 VAC•
A standard, no option MX code would be: MXOS.
In addition, the following options can be ordered for a new actuator or added to an existing MX:
M = Modulating•
I = Analog output (I/O), configurable as APT or ATT•
D = DDC Modbus network control•
F = FOUNDATION Fieldbus H1•
PV = Profibus DP_V1, RS-485•
PA = Profibus PA•
N = DeviceNet•
Z = SSMR (Solid State Motor Reverser)•
E = Negative switching/positive earth•
These other options can be supplied with the relay option boards; e.g. OA can be added to the I/O
analog output option. When ordered as such, a wiring diagram code can be supplied as “MXOAI.”
An MX supplied with an OB, Profibus DP_V1 network board, and SSMR can be ordered as
“MXOBPVZ.”
The MX wiring diagram matrix is shown on the following page. Please contact Flowserve Limitorque
