SNAP-PAC-ROK

Availability: Obsolete
OBSOLETE SNAP PAC Redundancy Option Kit
Data Sheet

Production Specification

*** NOTE: This part is OBSOLETE and no longer available. ***

The SNAP PAC Redundancy Option Kit includes the hardware and documentation you need to develop a control system with redundant controllers. Such a system provides an increased level of reliability that can survive single points of failure and improve your system’s mean time between failures (MTBF).

The kit includes a SNAP-PAC-SRA arbiter, a SNAP-RPSW redundant power switch, and the SNAP PAC Redundancy Option User’s Guide, form 1831. You will also need the following:

SNAP-PAC-SRA

Power Requirements

8–32 VDC, 4 W

Memory

16 MB RAM

Backup battery for real-time clock

Rechargeable (recharges whenever the arbiter has power). 5-year life when power is off.

Environmental
  Operating temperature
  Storage temperature
  Humidity

  

-0 °C to 60 °C
-40 °C to 85 °C
0% to 95% relative humidity, non-condensing

Wired Ethernet Network Interface

IEEE 802.3 network, 10Base-T and 100Base-TX. Automatic MDC/MDI-X crossover (Ethernet crossover cable not required for direct connection to PC).

Maximum Ethernet Segment Length

100 meters with Category 5 or superior UTP
For 100 Mbps at this distance, use Category 5 or superior solid UTP.

Serial Interfaces (2)

RS-485 twisted pair(s), with shield

Serial Data Rates

300 baud to 230.4 Kbaud

SNAP-RPSW

Max Switch Volts

32 VDC

Max Switch Current

4 amps DC at 70 °C

Operating Range

VDC

Switch Control (normally closed):

  
Off 8–32 VDC (3 mA–15 mA)
On < = 2 VDC (< 0.5 mA).

SNAP-PAC-S1 Controller Firmware

This download contains current firmware for the SNAP-PAC-S1 and SNAP-PAC-S1-FM controllers. Current firmware for all SNAP PAC brains and controllers is available in a single download here.

See the README document for information on changes and fixes in the current version of this product's firmware.

To install firmware, use the most recent release of PAC Manager (you can download the latest version from the Opto 22 website). Older versions of PAC Manager cannot install certain levels of firmware on controllers and brains shipped after certain dates or with certain versions of firmware currently installed on them.

SNAP S-series controllers shipped after February 22, 2022 shipped with new Ethernet components, PAC firmware R10.4d (or higher), and new bootloader firmware. For more information about minimum firmware requirements and installation requirements, review the README document.

SNAP S-series controllers shipped after April 2, 2018 shipped with new flash components, PAC firmware R9.5g (or higher), and new bootloader firmware. Lower versions of firmware are not compatible with these controllers. For instructions on recovering controllers that are accidentally installed with lower versions of firmware, review the README document.
