Uses & Applications

Overview

Totally configurable safety controller monitors numerous safety devices such as E-stop buttons, interlocking switches, safety light screens, two-hand controls and rope pull switches.

  • 22 input terminals can monitor both contact-based or PNP solid-state outputs from Banner devices or any other manufacturers
  • Each input can be a non-safety input, or configured for Control Reliability or Category 2, 3 or 4 safety circuit performance per ISO 13849-1
  • 3 pairs of solid-state safety outputs rated at 0.75A each (24V dc) with selectable one- or two-channel external device monitoring and ON-delay or OFF-delay
  • 10 configurable auxiliary status outputs track inputs, outputs, lockout, I/O status and other functions
  • Easy configuration with built-in front panel LCD display or PC Interface
  • Live Display and a Fault Log provide real-time system and fault history identification
  • Controller is designed to meet stringent standards including Safety Integrity Level (SIL) 3 per IEC 62061 and IEC 61508, and Category 4 Performance Level (PL e) per ISO 13849-1

Product Specifications

Safety and Non-Safety Inputs (22 terminals)Input ON threshold:greater than 15V dc (guaranteed on), 30V dc max.
Input OFF threshold:less than 5V dc (guaranteed off with any 1 fault), –3V dc min.
Input ON current:8 mA typical @ 24V dc, greater 2 mA (guaranteed with 1 fault); 50 mA peak contact cleaning current @ 24V dc
Sourcing current:30 mA minimum continuous (3V dc max. drop)
Input lead resistance:300 ohms max. (150 ohms per lead)
Power24V dc, ± 20%

0.4 A (controller only), 5.9 A (all outputs ON @ full rated load)



The Controller should be connected only to a SELV or PELV power supply.
Safety Outputs (6 terminals, 3 redundant outputs)Rated output current:0.75 A max. @ 24V dc (1.0V dc max. drop)
Output OFF threshold:0.9V dc typical (1.2V dc max. guaranteed with 1 fault)
Output leakage current:50 μA max. with open 0V
Load:0.1 μF max., 1 H max., 10 ohms max. per lead
Status Outputs (10 terminals)Rated output current:0.5A @ 24V dc (individual), 1.0 A @ 24V dc (total of all outputs)
O1 to O8 (General Purpose) Output OFF voltage:less than 0.5V dc (no load)
O9 and O10 (Monitored Mute Lamp) Output OFF voltage:internal 94 kohms pull up to V supply
O9 and O10 (Monitored Mute Lamp) Output ON/OFF threshold:15V dc +/-4V dc @ 24V dc supply
Note:For O9 and O10, if a short circuit or other fault condition causes the output to drop below this threshold while the output is ON, a lockout will occur. If an open circuit or other fault condition causes the output to rise above this threshold while the output is OFF, a lockout will occur.
Response and Reaction TimesResponse time (ON to OFF):10 milliseconds max. (with standard 6 milliseconds debounce; this can increase if debounce time increases. Refer to the configuration summary for actual response time.)
Reaction time (OFF to ON):400 milliseconds max. (with manual reset option)
Reaction time (OFF to ON):400 milliseconds max. plus input debounce time (auto reset)
Onboard LCD Information Display—Password RequirementsPassword is not required:

Run mode (I/O status)

Fault (I/O fault detection and remedial steps)

Review configuration parameters (I/O properties and terminals)

Password is required:

Configuration mode (create/modify/confirm/download configurations)
Environmental RatingNEMA 1 (IEC IP20), for use inside NEMA 3 (IEC IP54) or better enclosure
Operating ConditionsTemperature range:0° to +55° C
Mechanical StressShock:15 g for 11 milliseconds, half sine, 18 shocks total (per IEC 61131-2)
Bump:10 g for 16 milliseconds, 6000 cycles total (per IEC 61496-1)
Vibration:3.5 mm occasional / 1.75 mm continuous @ 5Hz to 9 Hz, 1.0 g occasional and 0.5 g continuous @ 9 to 150 Hz: (per IEC 61131-2) and 0.35 mm single amplitude / 0.70 mm peak-to-peak @ 10 to 55 Hz (per IEC 61496-1), all @ 10 sweep cycles per axis
EMCMeets or exceeds all EMC requirements in IEC 61131-2, IEC 61496-1 (Type 4), and IEC 62061 Annex E, Table E.1 (increased immunity levels)
Removable TerminalsScrew terminals:
Wire sizes:16, 18, 20, 22 or 24 AWG (0.20 – 1.31 mm2)
Wire strip length:5.00 mm
Tightening torque:0.23 Nm (2 in. lbs) nominal
Tightening torque:0.34 Nm (3.0 in. lbs) maximum
Clamp terminals:
Wire size:16, 18, 20, 22, or 24 AWG (0.20 – 1.31 mm2)
Wire strip length:9.00 mm
Important:The clamp terminals are designed for 1 wire only. If more than 1 wire is connected to a terminal, a wire could loosen or become completely disconnected from the terminal, causing a short.
