Control Signal and Relay Contacts Fiber MUX

Model #: FOM-9010 | FOM-9011 | FOM-9012

FOM-9010 | FOM-9011 | FOM-9012

The FOM-9010, FOM-9011 and FOM-9012 fiber optic isolator\modem cards provide uni-directional transport of low-level control or contact status signals. The status of all signals is shown on front panel indicators in addition to power supply and optical link status for each card.

The FOM-9010 can be used with contact closure sense or voltage inputs. The voltage input mode will accept polarity sensitive TIA-232, TTL, or TIA-422 state indications as well as sensing AC or DC voltages for simple presence. Each of the 12 input channels can be configured individually. Note that while the unit accepts certain electrical data standards, these units are not suitable for data use. Any data activity is simply viewed as an AC voltage and will be identified as being ‘on’

The FOM-9011 has all 8 channels fixed as Form C solid state contacts. The NC contact remains shorted to the C contact even with the FOM powered off.

The FOM-9012 supports Form A or Form B solid state contacts on the output channels. Each of the 12 channels can be configured individually and the Form B contacts remain shorted even with the FOM powered off.

The user can achieve complete electrical isolation for control and status signal in areas of high electrical noise or in/out of RF shielded enclosures (SCIF). The fiber optic cable is not susceptible to induced impulse noise and since signal ground is not carried over the link, the signal is not affected by elevated ground potential from lightning or other sources. The fiber optic cable enhances privacy of communications. A typical link consists of a FOM-9010 at one end and a FOM-9011 or FOM-9012 at the opposite end.
