Product Overview The SEL-2523 Annunciator Panel is an advanced annunciator panel that allows complete alarming, notification, reporting, and communication. The SEL-2523 supports many of the standard ISA-18.1 annunciator sequences. It comes standard with 36 alarm windows that can be independently programmed to alarm through contact inputs or communications. The SEL-2523 is designed to read and acknowledge alarms locally or remotely. Field Configurable Alarm Window Labels Each Column and Row Are Labeled for Easy Identification Super Bright LEDs Front EIA-232 Port for Easy Access to Settings and...

Automation The SEL-2523 Annunciator Panel makes it easy to automate a system-wide alarming station. The SEL-2523 comes standard with remote bits, timers, latches, and SELOGIC® variables. Use the logic to replace traditional panel alarms and latching relays, and to eliminate redundant wiring. Eliminate RTU-to-relay wiring with 40 remote control bits. Set, clear, or pulse remote control bits via serial port commands. Program the remote bits into your control scheme with SELOGIC control equations. Use remote bits for SCADA-type control operations, e.g., alarm trigger, acknowledgement, and device...

Integration The SEL-2523 Annunciator Panel is equipped with three independently operated serial ports: one EIA-232 port on the front and two EIA-232 ports on the rear. An additional EIA-232 or EIA-485 port is available as an ordering option. The SEL-2523 comes standard with ACSELERATOR QuickSet software to aid in setting the SEL-2523. The SEL-2523 supports settings from a standard ASCII terminal. The SEL-2523 is designed to easily establish communications to the following: ➤ Connected computers, modems, and protocol converters ➤ An SEL-3530, SEL-3364, or SEL-2032 ➤ SCADA serial ports, and/or...

Configuration and Commissioning The included ACSELERATOR QuickSet software simplifies device configuration in addition to providing the following commissioning and analysis support for the SEL-2523 Annunciator Panel: ➤ Access settings creation help online ➤ Organize settings with the device database manager ➤ Load and retrieve settings using a simple PC communications link ➤ Analyze SER records to verify alarm operation (see Figure 8) ➤ Use the PC interface to remotely retrieve reports and other system data ➤ Monitor alarm operation and status during commissioning tests ➤ Operate and monitor...

Time Synchronization The SEL-2523 Annunciator Panel can be timesynchronized through several different time sources. The IRIG-B input is the most accurate, and can be wired either through the separate IRIG-B input (see Figure 9) or through Port 3 on pins 4 and 6. The time code input synchronizes the SEL-2523 control inputs to within ±1 ms and all other SER time-stamped data to ±4 ms of the time-source input. Figure 12 shows the location of the IRIG-B ports on Card Slot 1. The SEL-2523 can also be time-synchronized through DNP via any of the rear serial ports set to “DNP” protocol. Although the...
