1 Control and Alarm Voltage sense, open collector, or contact inputs Features: FOM-00: Voltage Sense, Open Collector, or Dry Contact Inputs. State Detection for TIA-, TIA-, and TTL Signals. FOM-0: SPDT Form C Contact Closures FOM-0: SPST Form A (Normally Open) or Form B (Normally Closed) Contact Closures Each channel can be individually programmed as Form A or Form B Description The 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-0 and FOM-0 have the option to send optical status only back to the FOM-00. Applications 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-00 at one end and a FOM-0 or FOM-0 at the opposite end. The FOM-00 can be used with dry contact closure sense or voltage inputs. The voltage input mode will accept polarity sensitive TIA-, TTL, or TIA- state indications as well as sensing AC or DC voltages for simple presence. Each of the 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-0 has all channels fixed as Form C solid state contacts. The NC contact will short to the C contact when the FOM powered off or loses the fiber link. The FOM-0 supports Form A or Form B solid state contacts on the output channels. Each of the channels can be configured individually and the contacts revert to their switch-selected state upon loss of power or fiber link.

This only applies if the Detection Mode switch is set for Voltage. If the Detection Mode switch is set for dry Contacts / Open Collector then this switch has no function. Voltage detection is not polarity sensitive. Voltage detection is polarity sensitive. B lead must be positive with respect to A lead for on.

Power must be cycled after changing this setting. optics are active in bidirectional optical link allowing the FOM- 00 to display the status of the FOM-0 or FOM-0 local optical signal. Unit is only. The OPTICS led will not light, as there is no expected signal at the local optical connector. If there is a signal present the OPTICS led will flash red, indicating that there is a signal attached to the FOM-00 when one was not expected. When the link is in this mode, there is no reporting of the signal status from the far end. S.: No Function S.: Display Test This setting will cause the front panel display to flash each of the indicators an alternating red and green for verification purposes. The unit continues to function normally - only the display is affected. Normal indicator operation All indicators alternately flash red or green.
